RIDGELY B. HILLEARY AND CHESTER BRADFORD, OF INDIANAPOLIS, INDIANA.

PNEUMATIC ELEVATOR AND WEIGHER.

SPECIFICATION forming part of Letters Patent No. 706,054, dated August5, 1902.

Application filed December 18,1901. Serial no; 86,343. (No model.)

To all whom it may concern:

Be it known that we, RID GELY B. HILLEARY,

and CHESTER BRADFORD, citizens of the United States, residing atIndianapolis, in the county of Marion and State of Indiana, haveinvented certain new and useful Improvements in Pneumatic Elevators .andW'eighers, of which the following is a specification.

Our present invention relates to that class of machines commonly used inconnection with threshing-machines for handling grain, an example ofwhich is shown in Letters Patent offthe United States No. 623,109, datedApril 11, 1899; and it consists in a means for steadying and bracing theweigher and holding it in proper position at whatever elevation it maybe adjusted.

Said invention will be first fully described and the novel featuresthereof then pointed out in the claims.

Referring to the accompanying drawings,

which are made a part hereof and on which similar reference charactersindicate similar parts, Figure 1 is a side elevation of a pne u-' maticelevator and weigher provided with our said invention, a second positionbeing indicated by means of dotted lines; Fig. a view on asomewhat-enlarged scale as seen from the dotted line 2 2 in Fig. 1, thetelescopic pipe and frame-bars being shown in section and the remainderof the parts shown in elevation;.Fig. 3, a detail sectional-view.

of the yoke to which the brace-rod is hinged on a still further enlargedscale; Fig. 4, a detail sectional view of the eye through which thebrace-rod passes, and Fig. 5 a detail elevation of said eye.

The housingor boot 1, the vertical pipe 2, the supporting turn-table 3,the mast 4, the outwardly-extending telescopic pipe-sections 5 and 6,the telescopic frames 7 and 8, the elevating and lowering cable 9, theseparat- As heretofore in such machines, the weighing and baggingdevices are suspended from the ears on the separating-head by pivots orpendicularity of said parts, which is necessary to the accurateoperation of the weigher. Inthe Patent No. 623,109, above referred to,the means of holding the weigherand parts attached thereto inperpendicular position consisted of friction-plates-at the points wheresaid pivots are located, said pivots consisting of screw-bolts whichwere intended to be loosened when the relative positions were to beshifted and retightened when'the desired positions were attained. Inpractice,

however, we have found that it is diflicult to secure the requiredrigidity of the apparatus by means of such screw-bolt pivots alone, andit is more difficult to secure operatives who 'wlllproperly manipulatethem. By means of our invention, which consists of the-bracing apparatusnow presently to be described, it is permissible to leave the pivots plooseand depend upon the said bracing-apparatus, which is much moreeasily and conveniently manipulated, both because thereis but oneclamp-screw to be so manipulated and because the position ofsaid-clamp-screw is in much'easier reach of the operatives than thepivots are or were. We have therefore se cured to the outer telescopicpipe 6, or preferably tolits frame 8, the yoke 20,,to which we havepivoted a brace-rod 21, which passes down through an eye 22, in whichthere is a clamp-screw 23. As will be best understood by an examinationof Figs. 2 and 3, the yoke 20 being rigidly secured to the outer endofthe telescopic structure and moving therewith is Well adapted to supportthe brace-rod, which is pivoted thereto by a pivot-bolt 24. Said yokealso may be arranged as a stop against which the casting 14=- may strikewhen the telescopic pipes are moved in to'their shortest length. The eye22 is firmly riveted to the receiving-hopper 13 below the weighingdrum11, and the lower end of the brace-rod 21 passes therethrough, and whenthe clampscrew 23 is applied said brace-rod is held very firmly therein.The lower end of the bracerod is curved, as shown in Figs. 1 and 4, sothat its lower end will not come in contact with the hopper 13 or theparts which are attached thereto.

As will be seen, this present apparatus does not in any Way interferewith the free and perfect operation of the weigher or scale apparatus,as it is'connected atthe one end to secured and held in positionrelatively to the weighing apparatus and a vertical position of saidweigher apparatus thus maintained whatever the relative position of theelevator apparatus may be.

2. The combination, in a pneumatic elevator and weigher, with theadjustable elevator-pipe and the weigher apparatus suspended thereto, ofa bracing apparatus consisting of a yoke 20, a brace-rod 21 connected tosaid yoke, a stud or eye 22 connected to the weigher apparatus frame andto which said brace-rod is connected, and a means whereby said bracerodcan be secured thereto at any desired position therein, substantially asset forth.

In Witness whereof we have hereunto set our hands and seals, atIndianapolis, Indiana, this 9th day of December, A. D. 1901.
